is the tank heated and filtered?
the tank is neither filtered or heated, i think it is too much work and money for a 5 gallon tank. i just change my water on a weekly basis and that hasn't given me any problems so far
That really isn't the right attitude to have towards your fish.
I don't really understand the statement of too much work.... I can understand the money part sorta.. but work.. well... I dunno about that.
You should really think about saving up to get a filter and a heater (if the water doesn't stay a consistant warmer temp that is).
Sorry, I didn't mean too much work. I have stated I change my water on a weekly basis. I meant it will take up too much space for a 5 gallon tank having both of those things. The water heater come in 50w and its too much for a small tank, and I've heard having water pump is too strong for these fishes. I think it is too much extra stuff that is not necessary if do weekly water changes and I live in a place where weather does not fluctuate much.
